Lower Intake Manifold Installation (3.0L) - Mazda B-Series 1997 Workshop Manual

ON-VEHICLE MAINTENANCE
Lower intake manifold
1. Lightly oil all bolts and stud threads before installation.
2. Clean the mating gasket surfaces of the lower intake
manifold and the cylinder head. Lay a clean shop rag in
the tappet valley to catch any gasket material. After
scraping, carefully lift the cloth from the tappet valley
preventing any particles from entering the oil drain holes
or the cylinder head. Use a suitable solvent to remove the
old rubber sealant.
Caution
Aluminum components gouge easily which can
cause gasket leaks. Always use care when scrap-
ing aluminum gasket surfaces.
3. If installing a new lower intake manifold, transfer the fuel
injectors, fuel supply manifold, engine coolant tempera-
ture sensor, thermostat, gasket and housing, heater
hose elbow and the water temperature indicator sender to
the new manifold.
4. Apply sealant to the intersection of the cylinder block and
